JUPITER, FL / May 13, 2021 / Dyadic International, Inc. (“Dyadic”, “we”, “us”, “our”, or the “Company”) (NASDAQ:DYAI), a global biotechnology company focused on further improving, applying and deploying its proprietary C1-cell protein production platform to accelerate development, lower production costs and improve the performance of biologic vaccines and therapeutics today announced its financial results for the first quarter of 2021 and highlighted recent Company progress.

“We continued to advance our science as well as make progress in a number of our animal and human health initiatives and third party R&D collaborations during the first quarter,” stated Mark Emalfarb, Dyadic’s Founder and Chief Executive Officer. “We filed two patent applications so far this year and anticipate filing one or more provisional patent applications during the balance of the year. We are excited to be advancing our proprietary COVID-19 vaccine candidate, DYAI-100, towards a first-in-human Phase 1 clinical trial, which remains on track to initiate by year-end. This will be a major milestone for both the company and our C1 technology platform. Potentially demonstrating both safety and preliminary efficacy using a protein manufactured from our proprietary and patented C1 cell line will de-risk and accelerate the adoption and use of our C1 technology platform for the development and production of vaccines and therapeutics globally. Additionally, a successful Phase 1 clinical trial with DYAI-100 will bring us a step closer to another one of our goals, which is to bring a more efficient vaccine and drug manufacturing process to help combat the COVID-19 pandemic. Through the use of C1, Dyadic is well-positioned to generate and deliver larger quantities of lower cost COVID-19 vaccines to the world’s population that continues to suffer due to the lack of access and affordability to safe and effective COVID-19 vaccines and therapeutics.”

Mr. Emalfarb continued, “In addition to advancing our own proprietary DYAI-100 vaccine candidate and our previously disclosed partnership with Medytox to develop next-generation COVID-19 variant vaccines, we have been engineering additional C1 cell lines to produce SARS-CoV-2 variant antigens for monovalent and multivalent vaccine candidates. The C1 produced antigen is also being evaluated by other parties, and there are a number of ongoing discussions with leading scientists, governmental agencies, pharmaceutical and biotechnology companies who are interested in using our C1 technology to develop and manufacture their COVID-19 vaccine candidates.

The potential of C1 to help meet global health challenges, such as COVID-19, was highlighted in a recent KOL fireside chat hosted by Dyadic. Regarding C1, Joris Vandeputte, D.V.M., President of IABS (International Alliance for Biological Standardization), stated, “Results show already today that C1 is able to produce large amounts of the receptor-binding domain of SARS-CoV-2 or even the complete spike, for different variants. It also glycosylates very well, which is a very time-saving element comparing to previous classical production times.” He continued that “the versatility of the system is really very appropriate to adapt the vaccines quickly to variants in case of need. And again, in our experience, C1 fits to almost any steel bioreactor, single-use bags, anywhere in the world where there is fermentation experience. Even in the case of nano-particles, the system allows high flexibility. …I would say that the C1 production system is not only a potential game changer in the global access to much needed vaccines, but also a must, we have to focus on.”

“The transformative potential of our C1 technology platform goes well beyond the COVID-19 pandemic, and in parallel to our COVID-19 initiatives, we remain focused on and are advancing C1 for several other human and animal health applications. During the first quarter, we entered four new funded collaborations with pharmaceutical and biotech companies, including our fully funded collaboration with TurtleTree Scientific to develop human growth factors. Importantly, as we continue to add new partners like TurtleTree, we are expanding the number of commercial opportunities for our C1 platform to address challenges in animal and human health globally. With such clear advantages for cost-effective and flexible scale commercial production, we believe, as do a growing number of partners, key opinion leaders and subject matter experts, that our C1 protein production platform presents a solution for more affordable and accessible therapeutics and vaccines worldwide,” concluded Mr. Emalfarb.

Recent Company Progress

COVID-19 Initiatives:

• Advancing the Company’s proprietary COVID-19 vaccine candidate (C1 produced SARS-CoV-2-S-RBD antigen), DYAI-100, towards a first-in-human Phase 1 clinical trial:
  • DYAI-100 is supported by a strategic collaboration with, among other parties, the IIBR and leading infectious disease scientists from Erasmus Medical Centre, University Utrecht, TiHo Hannover (scientists who were involved in the ZAPI program) to develop a temperature stable, safe and effective COVID-19 vaccine candidate that can be rapidly manufactured, in large quantities, at low cost, using standard microbial fermenters that are readily available globally.
  • In March 2021, the Company engaged CR2O, a contract research organization, to manage and support further preclinical and clinical development of DYAI-100. The animal GLP toxicology study began at the end of April 2021, the cGMP production of the C1 expressed SARS-CoV-2 RBD drug product has begun, and a first-in-human Phase 1 clinical trial is expected to begin by year-end.
  • There are a number of benefits the Company expects to come from the DYAI-100 Phase 1 clinical trial, including demonstrating that certain C1 produced proteins can be produced under cGMP conditions and are safe and tolerated in humans, which will be required by regulatory agencies such as the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA). Additionally, this will also serve as a proof of concept study for potential C1 manufactured next-generation monovalent and multivalent COVID-19 variant vaccine candidates that can be developed and manufactured rapidly, in large quantities, and more affordably.
• In parallel with advancing the DYAI-100 vaccine candidate towards a Phase 1 clinical trial, the Company has already started to engineer several C1 cell lines to produce several SARS-CoV-2 variant antigens, and has successfully expressed the South African, Brazilian, and UK variant antigens at high productivity and stability. The Company and its collaborators are working to produce RBD antigen and full spike proteins for additional COVID-19 variants.
• In March 2021, the Company expanded a vaccine development partnership with South Korea’s Medytox Inc. to co-develop C1 enabled COVID-19 variant vaccines and/or boosters (e.g., tetravalent or quadrivalent COVID-19 vaccine candidates) to immunize people against two or more of the current and future COVID-19 variants in Korea and Southeast Asia.
• In April 2021, the Company signed a separate fully funded research collaboration with CR2O to develop a COVID-19 antibody.

Human Health (Non-COVID) Collaborations:

• In February 2021, the Company initiated a fully funded collaboration with TurtleTree Scientific to develop several recombinant protein growth factors, which have the potential to play a critical role in tissue development and healing, including regenerative therapies.
• In March 2021, the Company signed a research collaboration with a new research partner to develop an antigen.
• In April 2021, the Company expanded its collaboration with IDBiologics and started a new fully funded collaboration to develop a second antibody.
• Collaborating with Jiangsu Hengrui Medicine and two top pharmaceutical companies for proof of concept studies designed to improve the production of biologic drugs, including bispecific antibodies, of therapeutic interest. Interim results have demonstrated these biologic drugs were expressed from C1 and there are ongoing discussions for advancing some of these projects towards potential clinical development.
• Continued progress in several ongoing collaborations to develop potential therapeutic candidates of commercial potential, including expressing two new bispecific antibodies and advancing two other antibodies which are entering the second stages for applications in oncology and autoimmune disease.
• Conducting a feasibility study with the University of Oslo for a potential influenza vaccine. Interim results demonstrated that C1 can express hemagglutinin at a high level, and most importantly, that C1 hemagglutinin induced a high level response of neutralizing antibodies in a mice study.

Animal Health Collaborations:

• In collaboration with a top global animal health company, initial studies have demonstrated production of two different antigens for a potential vaccine for an acute respiratory disease of birds. Interim results demonstrated that the antigens were effective at generating high antibody titers. An animal challenge study designed to evaluate protection against the acute respiratory disease is expected to start in June 2021.
• ZAPI held its Final Stakeholders Virtual Web Meeting on February 4-5, 2021, where positive results were reported from animal studies in mice, sheep, and cattle which evaluated the safety, efficacy, and protection of the C1 produced Schmallenberg virus (SBV) antigen. The C1 platform was selected by ZAPI to produce recombinant antigens after demonstrating far greater antigen productivity from C1-cells than insect (baculovirus) cells, the next leading expression platform, for both SBV and Rift Valley Fever Virus (RVFV). As previously disclosed, in the first quarter of 2021, ZAPI has provided the Company with additional funding to produce larger quantities of both the SBV and RVFV antigens to demonstrate commercial-scale viability of C1 produced SBV and RVFV antigens and to further optimize the use of C1 to produce recombinant protein subunit nanoparticle vaccines. Preliminary results have been very encouraging and continue to further support C1’s potential for use in developing nanoparticle vaccines in larger quantities at lower cost. Several positive outcomes have already originated from the ZAPI results, including several fully funded animal health projects and several SARS-CoV-2 vaccine collaborations, including Dyadic’s receptor-binding domain (RBD) antigen of the SARS-CoV-2 spike protein.

Corporate Highlights:

• The Company extended two non-exclusive research license agreements, including WuXi Biologics and an affiliate of a top pharma company, to continue their C1 research projects in a CDMO and manufacturing environment at their own facilities.

About Dyadic International, Inc.

Dyadic International, Inc. is a global biotechnology company which is developing what it believes will be a potentially significant biopharmaceutical gene expression platform based on the fungus Thermothelomyces heterothallica (formerly Myceliophthora thermophila), named C1. The C1 microorganism, which enables the development and large-scale manufacture of low-cost proteins, has the potential to be further developed into a safe and efficient expression system that may help speed up the development, lower production costs and improve the performance of biologic vaccines and drugs at flexible commercial scales. Dyadic is using the C1 technology and other technologies to conduct research, development and commercial activities for the development and manufacturing of human and animal vaccines and drugs, such as virus like particles (VLPs) and antigens, monoclonal antibodies, Fab antibody fragments, Fc-Fusion proteins, biosimilars and/or biobetters, and other therapeutic proteins. Certain other research activities are ongoing which include the exploration of using C1 to develop and produce certain metabolites and other biologic products. Dyadic pursues research and development collaborations, licensing arrangements and other commercial opportunities with its partners and collaborators to leverage the value and benefits of these technologies in development and manufacture of biopharmaceuticals. As the aging population grows in developed and undeveloped countries, Dyadic believes the C1 technology may help bring biologic vaccines, drugs, and other biologic products to market faster, in greater volumes, at lower cost, and with new properties to drug developers and manufacturers, and improve access and cost to patients and the healthcare system, but most importantly save lives.
